I come from a island where its common to pain with sand. About one hundred beach, around two hundred colors, green is hard to make.
I learned that local sand composition is very affected by local geology.

I mean it makes sense that the sand is made of the same stuff as your local rocks, that's where it came from. Sure it washes around a bit in the surf but it's not like it's floating around the world on the ocean currents, at least not in massive quantities. I'm sure there are bits stuck in driftwood or whatnot but the vast majority should sink to the bottom.
